Stress Effects on Magnetic Properties of Amorphous Microwires Subjected to Current Annealing

Abstract: Abstract. Effects of current annealing on magnetic hysteresis properties and magnetoimpedance (MI) of glass-coated amorphous microwires with nominal composition of Co71Fe5B11Si10Cr3 and small positive magnetostriction were investigated with the purpose to control the magnetic anisotropy. We have demonstrated that current annealing can produce a controllable change in the easy anisotropy direction from almost axial to circular, depending on the annealing time. The induced magnetization configuration is very sen… Show more

“…Полученная возможность изменения направления легкой оси анизотропии с помощью токового отжига в проводах с положительной магнитострикцией открывает широкие перспективы для применения в сенсорах механических напряжений, работающих в высокочастотном диапазоне. Такая наведенная магнитная анизотропия также представляет большой интерес для повышения чувствительности МИ [33] и, что более важно, создает условия для проявления эффекта сверхвысокого стрессчувствительного МИ без использования дополнительных магнитных полей (или токов) смещения.…”
